Nice Tribute
A group of ‘Net engineers got together to talk about Terry Pratchett and came up with a plan to honor his memory – add GNU Terry Pratchett to the overhead stream on servers.
That generated the GNU Terry Pratchett website with instructions for adding the tag to server software.
If you use WordPress for your blog, there’s a plug-in that adds it to your static pages.
The reference is to a tradition explained in Going Postal, one of Sir Terry’s Discworld novels.
Don’t expect to see GNU Terry Pratchett all over unless you look at packet headers and meta data, because it is not intended to increase the overhead or appear to most people.
